DENTAL FLASK PRESS.

Application filed December 13, 1926. Seria1 No. 154,571.

lustrate an application of my invention:

Fig. 1 is a front elevational view of a dental flask press embodying my invention, showing two flasks in position thereon;

Fig. 2, a view similar to Fig. 1, showing a single flask;

Fig. 3, a part side elevational and a part sectional view, 'the section showing the compression screw and its cooperating head;

Fig. 4, a rear elevational view Fig. 5, a top plan view and Fig. 6, a detail perspective view, showing the compression screw and its supporting means.

Referring to the drawings, the press embodying my invention includes a frame having a base portion 5 and an upright member or standard 6 extending vertically from an edge of the base. The base and the upright are preferably made as an integral structure of any suitable metal.

As illustrated, the standard or upright 6 is formed with a vertically extending centrally disposed slot 7, the said slot 7 extending for almost the entire length of the upright. Arranged adjacent to the slot and on opposite sides thereof, I provide toothed or notched portions 8, said portions 8 being adapted to cooperate with a carrier for a compression screw, hereinafter described.

The ear face of the upright is cut away to form a track 9, on which the compression screw carrier is slidably mounted. 10 designates guide flanges adapted to be engaged by a portion of the carrier when the parts are as sembled for use.

The compression screw carrier, as illustated and as preferred, includes two spring metal members 11 and 12, said members having their outer ends entered in a head 13 and each provided with an opening through which a compression screw 14 is passed. Head 13 also ias a centrally disposed threaded opening 15 adapted to receive the threaded portion of the compression screw.

The compression screw, in addition to its threaded portion, is provided with a head 16,

and an operating handle 17Iprojected through the head. The carrier member 11, atits inner end, is inclined upwardly and formed ,with teeth engagingmembers 18, adapted to cooperate with the toothed'portions 8 of the standard when placed in position thereon. Said-memberll is further provided with a centrally disposed guidemember the latter being adapted to be inserted in the slot 7 of the standard 6.

The second spring member of the carrier structure has its inner portion passed through the slot, and at its inner end is provided with a head 20 and an inwardly projecting portion 21.

The carrier is adapted to be mounted on the 7 standard, and when in operative position thereon, a portion of the head 20 of member 12 rests on the track 9 of the standard, while the inwardly projecting portion 21 is positioned in the slot 8, engaging the walls thereof, and aids in guiding the carrier on the standard.

The construction provides simple and efficient means for clamping one or more dental flasks A in the desired position on the press, and the invention also provides a construction that may be easily manipulated to readily adjust the parts to the desired operative positions.

What I claim is:

1. In a dental flask press, a frame including a base portion and a single upright member extending vertically from the base portion, a compression screw carrier slidably mounted on the upright, and having spring means cooperating with the upright for look ing the carrier in operative position on the upright and a compression screw on said carmen 2. In a dental flask press, a frame including a base portion and a single slotted upright extending vertically from the base portion and having toothed portions adjacent the slot of the upright, compression screw carrying means adj ustably mounted on the upright and having means projecting through the slot and,

cooperating with the toothed portions and a compression screw on said carrying means.

3. In a dental flask press, a frame including a base portion and single slotted upright member extending vertically from the base portion, a compression screw carrier includ ing a member entered in the slot of the up right and slidably mounted on the upright, a compression screw on the carrier, and oooperating means on the upright and carrier for locking the carrier in operative position on the upright.

4:. In a dental flask press, a frame including a base portion and an upright member extending vertically from the base portion, a compression screw carrier slidably mounted on the upright, and a compression screw on said carrier, said carrier including two spring members engaging the upright.

5. In a dental flask press, a frame including a base portion and an upright member extending vertically from the base portion, a compression screw carrier slidably mounted on the upright, a compression screw on said carrier, said carrier including two spring members engaging the upright, and cooperating means on the upright and the spring members for locking the carrier in operative position on the upright.

6. In a dental flask press, a frame including a base portion and a slotted upright member extending vertically from the base portion and having toothed portions adjacent the slot, a compression screw carrier adjustably mounted on the upright including spring metal members, a threaded head on the carrier, a compression screw in the head, one of said spring members having means for engaging the toothed portions of the upright,

and the other spring member having means" CLAYTON J. REYNOLDS.
